Unusual course of the median nerve

One extremely unusual observation has been reported in this case report. During dissection of left hand of an adult human cadaver we found median nerve passing through the substance of flexor retinaculum. Median nerve coursed through the entire extent of flexor retinaculum in a fascial canal. No other structure was found along with nerve in the fascial canal. After emerging from the flexor retinaculum median nerve took its usual course in the hand. To the best of our knowledge this kind of variant median nerve course has not been described in published literature.
